    摘要: An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue thereby causing current to flow through the tissue and, as a result, generate heat within the tissue. The surgical instrument can further comprise a fluid circulatory system embedded within at least a portion the end effector wherein, in at least one embodiment, the fluid can be dispensed from the fluid circulatory system and onto the jaws of the end effector and/or the tissue positioned between the jaws.
